Low-power-consumption wireless intelligent water meter controlled by magnetic induction switch

Abstract

The invention discloses a low-power-consumption wireless intelligent water meter controlled by a magnetic induction switch. The meter comprises a flow metering module, a processing module, an NBIOT module, a short-distance communication module, a switch valve module and a magnetic induction switch module, wherein the flow metering module is connected with the processing module, and the switch valve module is connected with the processing module and a water meter valve; the magnetic induction switch module is connected with the processing module and controls the NBIOT module and the Bluetooth module to be turned on and turned off, and the NBIOT module and the short-distance communication module are connected with the processing module. The meter is advantaged in that the water quantity information of the water meter can be remotely obtained through the NBIOT module, the water quantity information of the water meter can also be obtained on site through the short-distance communication module, reading reliability of the water quantity information of the intelligent water meter is guaranteed, and the application range of the intelligent water meter is expanded; opening and closing of the NBIOT module and the Bluetooth module are controlled through the magnetic induction switch module, power consumption of the water meter is reduced, and the service life of the water meter is prolonged.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to a low-power wireless intelligent water meter controlled by a magnetic induction switch. Background technique [0002] With the development of communication technology, various communication modules are more and more widely used in metering equipment, including smart water meters, which can directly send water volume information to the server through communication modules, without manual on-site meter reading. Among them, the most widely used The most important thing is the NB-IOT communication module, and the existing smart water meter only has one kind of communication module. The communication between the smart water meter and the server is established under the condition that the communication base station and the communication module are both working normally, which limits the application of the smart water meter. Scope, when there is a lack of communication base station...

AI Technical Summary

Problems solved by technology

The disadvantage of the above patent documents is that the smart water meter can only rely on the NB-IOT communication module to exchange information with the server. When there is no NB-IOT communication base station or there is a problem with the NB-IOT communication module, the smart water meter cannot upload water volume information. It is also unable to receive the control information from the server, which limits the application range of smart water meters
